MULTI-SCALE COUPLED PORE STRUCTURE MODELING APPROACH TO CONCRETE; SKETCH OF STRATEGY AND METHODOLOGY, AND EXAMPLES

Pore structure in concrete gives router for the transport of harmful substance from outside into concrete, which deduce deterioration of concrete or corrosion of steel reinforcement. Therefore, it plays an important role of characterization of pore structure in durability prediction of concrete. Proper physical computer simulation approach, like concur-rent algorithm-based systems, renders an economic alternative for material character and properties prediction instead of time-consuming experimental investigation. In this paper, different level of pore structure characterization approaches has been investigated. Furthermore, the applicability of two concurrent algorithm-based simulation systems, i.e. SPACE and HADES, in pore structure assessment of concrete is analyzed. A method coupled micro-level and meso-level of pore structure characterization in model concrete is revealed. Both successful application results examples and future work will be discussed in this paper.
